Product Details

■ Product Overview

The lightning protection component tester is suitable for zinc oxide surge arresters. ( Varistor ), Measurement of DC parameters for overvoltage protection components such as metal‑ceramic two‑ and three‑electrode discharge tubes and vacuum surge arresters. It can also serve as a voltage‑regulating or constant‑current power supply. , Used for other purposes.

■ Product Features

It features high-voltage short-circuit protection, overcurrent protection, high-voltage presetting, and range adjustment. , The high-pressure self‑relief time is less than 0.5 Seconds.

. It has a self-diagnostic function.

. The measurement data is provided by 3 1/2 LCD Digital display , High accuracy and excellent reliability.

. During measurement , The measurement range can be preset. , And during measurement, it emits an audible alert when an overrange test is detected. , Suitable for device sorting and inspection classification.

. Select continuous measurement , It can perform continuous testing on batches of test specimens.
